Heritage Guns' Comment

This superb gun was made shortly after John Robertson bought Boss & Company and developed it into probably the most exclusive London gunmaker of its time. With its toplever, baraction locks and superb Sumner engraving, this gun represents the departure from Robertson’s predecessor, EF Paddison’s very traditional preference for back actions, sidelevers and rotary underlevers.
On taking over Boss & Co, Robertson changed the style of the guns to appeal to more modern tastes and this gun reflects many of the changes he introduced although interestingly, it is not stocked to the fences.
The gun had been rebarrelled in 1978 and proofed for 2 ” ammunition so we have had the gun reproofed for 2 ” ammunition and following a sensitive restoration, we are pleased to be able to offer a beautifully balanced gun for game or clays.
Presented in a relined oak & leather case complete with Maker’s labels
and some accessories including a striker pot with spare strikers.

Straight Hand Stock and Splinter Forend is crafted from highly figured walnut, thought to be original or possibly a vintage replacement. The stock is lightly cast-off for a right-handed shot, features a vacant white metal oval and well defined drop points and is finished with a chequered butt. There is a very small inlet repair to the edge of the left underhorn. The forend wood has two inlet repairs to its edge and features a finely engraved steel tip and diamond.
Highly Figured Walnut

The approx 26 lines per inch chequering has been refreshed to its original sidelock pattern.
.The stock is finished with a traditional linseed oil based preparation as used on best guns by one of the top English makers. This finish uses no grain fillers to achieve its deep, smooth lustre, only many hours of alternate build and flatting off of the surface.
